Students cleaned out the crankcase, put the flywheel back on, cleaning contact points as they worked their way out today, HUGE spark. Put the engine back on, now they are looking for the rings, going to check the stickiness on the carbeurator throttle, and will be looking for the broken rings, a gas tank (missing), and some throttle cables to replace the rusted and stuck ones.
The spark really got them going today.
